Help with REGEX in transforms.conf

I have a requirement to route events to separate indexes based on two conditions.
1) must contain the string PI_EVENT
2) Get the value contained in the value

The index it needs to be routed to will be the value of businessdomainid + -sec
(ex. businessdomainid1-sec)

How do I write my regex and format statement to have this work?

Here's my transforms.conf so far

[Security]
SOURCE_KEY = _raw
DEST_KEY = _MetaData:Index
REGEX=(?m)\<BusinessDomainId\>(BusinessDomainId1|BusinessDomainId2|BusinessDomainId3)\</BusinessDomainId\>|<LogEventTypeCode>PI_EVENT</LogEventTypeCode>
FORMAT=$1

Sample event

<ELLogInputMessage> 
        <Header> 
            <LogEventTypeCode>PI_EVENT</LogEventTypeCode> 
            <LogSeverityCode>CRITICAL</LogSeverityCode> 
            <LogEventDateTime>2014-05-06T23:59:59.9999999-05:00</LogEventDateTime> 
        </Header> 
        <SourceInformation> 
            <EAPMId>1</EAPMId> 
            <HostMachineName>HostMachineName3</HostMachineName> 
            <HostEnvironmentName>HostEnvironmentName3</HostEnvironmentName> 
            <ComponentId>ComponentId3</ComponentId> 
            <ComponentName>ComponentName3</ComponentName> 
            <ApplicationEventCorrelationId>ApplicationEventCorrelationId3</ApplicationEventCorrelationId> 
            <UserId>UserId1</UserId> 
            <UserSrc>UserSrc1</UserSrc> 
            <BusinessDomainId>BusinessDomainId1</BusinessDomainId> 
            <BusinessDomainName>BusinessDomainName1</BusinessDomainName> 
        </SourceInformation> 
        <DataAccessInformation> 
            <DataCompId>DataCompId2</DataCompId> 
            <TypeOfAccess>VIEW</TypeOfAccess> 
            <SubjectOfInterest> 
                <SubjectId>SubjectId13</SubjectId> 
                <SubjectName>SubjectName13</SubjectName> 
                <SubjectDomainName>SubjectDomainName3</SubjectDomainName> 
            </SubjectOfInterest> 
            <AccessDateTime>2014-05-06T23:59:59.9999999-05:00</AccessDateTime> 
        </DataAccessInformation> 
        <DetailedLogInformation>anyType</DetailedLogInformation>
</ELLogInputMessage>

Your current regex will match events that contain either or tags, but necessarily both. Try the following.

REGEX=<LogEventTypeCode>PI_EVENT</LogEventTypeCode>[\s\S]*<BusinessDomainId\>(BusinessDomainId1|BusinessDomainId2|BusinessDomainId3)\</BusinessDomainId\>
FORMAT=$1-sec
